Part Descriptions

LP14684-2   Lysozyme
Lysozyme is an enzyme (EC 3.2.1.17), commonly referred to as the body's own antibiotic since it kills bacteria. It is abundantly present in a number of secretions, such as tears. This protein is present in cytoplasmic granules of the polymorphonuclear neutrophils (PMN) and released through the mucosal secretions (such as tears and saliva). They can also be found in high concentration in egg white. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP32397-9   Ab.IgG4
IgG4 is the least common subtype of IgG, and it has a variety of functions. In the context of allergic disease it is thought to have an immune-inhibitory role in preventing anaphylaxis and is commonly known as a “blocking” antibody. IgG4 binding to an allergen can compete with IgE-mediated binding, thereby inhibiting the activation of mast cells and basophils and IgE-mediated presentation to T-cells. Measuring IgG4 and its ratio to IgE has a role in monitoring allergen specific immunotherapy [PMID: 26023323] . IgG4 is also thought to have a role in autoimmunity and be involved in a less defined entity known as IgG4-Related Disease, a chronic immune-mediated fibroinflammatory disorder that often manifests with tumor-like masses .[https://www.merckmanuals.com/professional/musculoskeletal-and-connective-tissue-disorders/igg4-related-disease/igg4-related-disease] Source: Regenstrief LOINC
